Performance Evaluation of a Multi-Branch Liquid-Gas Pipe Separator using Computational Fluid Dynamics
(Master thesis, 2018)The present thesis aims to evaluate the performance of a multi-branch gas-liquid separator by means of 3D computational fluid dynamics (CFD). Thus, numerical simulations of the two-phase system were performed using various ... -
Performance evaluation of a multi‑branch gas–liquid pipe separator using computational fluid dynamics
(Journal article; Peer reviewed, 2019)The present paper aims to evaluate the performance of a multi-branch gas–liquid pipe separator by means of 3D computational fluid dynamics. This type of separator is attractive for deepwater subsea hydrocarbon fields due ... -
Performance of a fully grouted GFRP rock bolt under combined pull and shear loading
(Chapter, 2020)Glass Fiber Reinforced Polymer (GFRP) rock bolts is gaining attention, as an alternative to steel bolts, for permanent rock support in civil underground infrastructures like road tunnels. GFRP holds many advantages for ... -
Performance of Fully Grouted GFRP Rock Bolt in Combined Pull and Shear
(Master thesis, 2019)Glass Fiber Reinforced Polymer (GFRP) bjergsikringsbolte har fået opmærksomhed, som et alternativ til stålbolte for permanent bjergsikring. GFRP har mange fordele til dette formål, herunder lavere vægt og miljøbelastning ... -
Performance of Identical Rockbolts Tested on Four Dynamic Testing Rigs Employing the Direct Impact Method
(Peer reviewed; Journal article, 2021)Impact drop tests are routinely used to examine the dynamic performance of rockbolts. Numerous impact tests have been carried out in the past decades on independently designed, constructed and operated testing rigs. Each ... -
Performance of Internals in Three-Phase Tank Separators
(Master thesis, 2013)The thesis work focused partly on sizing a three phase vertical and horizontal separators without internals and with internals at different pressures and the performance of internals to increase the capacity and efficiency ... -
Performance of Unbound Pavement Materials in Changing Moisture Conditions
(Chapter, 2020)Expected climate changes will in many areas represent a shift towards increased precipitation and more intense rainfall events. This may lead to increased moisture within road structures and possible overloading of road ... -
Permafrost as a first order control on long-term rock-slope deformation in (Sub-)Arctic Norway
(Peer reviewed; Journal article, 2021)Assessing initiation of rock-slope deformation and paleo-slip rates of rockslides is important to understand the impact of climate variability - in particular permafrost changes - on rockslide activity. Norway, with 6–6.5% ... -
Permafrost controls the displacement rates of large unstable rock-slopes in subarctic environments
(Peer reviewed; Journal article, 2022)Determining the link between permafrost and the displacement rates of large unstable rock-slopes (LURSs) is fundamental for understanding future hazard scenarios and establishing appropriate management strategies. From an ... -
Permafrost distribution in steep rock slopes in Norway: measurements, statistical modelling and implications for geomorphological processes
(Journal article; Peer reviewed, 2019)Permafrost in steep rock slopes has been increasingly studied since the early 2000s in conjunction with a growing number of rock slope failures, which likely resulted from permafrost degradation. In Norway, rock slope ... -
Permeability Estimation from CT-scans of Extracted Core Data using Convolutional Neural Networks
(Master thesis, 2022)This thesis evaluates the possibility of automated permeability estimation by utilizing the information obtained from whole core 2D and 3D CT-scan images of wells on the Norwegian continental shelf. To evaluate this ... -
Permeability Prediction from Acoustic Velocity
(Master thesis, 2016)Permeability is estimated in the middle Jurassic Garn Fm. in the Haltenbanken area in the Norwegian Sea by combining the Kozeny-Carman model for permeability estimation with Raymer s model for porosity estimation. The ... -
Permian-Triassic Depositional Systems in the Norwegian Sea Areas
(Doctoral theses at NTNU;2020:195, Doctoral thesis, 2020)Upper Permian deposits from the eastern margin of the Helgeland Basin, offshore Norway, are known to contain two organic-carbon-rich (OCR) intervals within the Lower Turbidite Unit. These intervals were so far not proven ... -
Permo–Triassic sedimentary fills and tectonic phases off Mid Norway: seismic investigation of the Trøndelag Platform
(Peer reviewed; Journal article, 2020)Seismic interpretation (2D and new 3D surveys) has been used to investigate sedimentary fills and timing of tectonic activity offshore Mid Norway. This study was focused on upper Permian and Lower Triassic sedimentary basin ... -
Petrogenesis of Fe-Ti-P rich rock in the Siljan-Hvarnes Intrusion, S.E. Norway
(Master thesis, 2021)Siljan -Hvarnes-intrusjonen ligger i Vestfold Graben, i S.E. Norge. Intrusjonen ble formet for 277 M. år siden under den mest aktive vulkanske perioden i dannelsen av Oslo Graben. Intrusjonen består av flere sammenflettede ... -
Petrographical analysis of the diagenesis and reservoir quality of sandstones from the Nordmela and Fruholmen formations. - A study of the Fingerdjupet Sub-Basin in the Barents Sea.
